To al( whom it may concernaif Y i, j Bef it knownthatfl, .Gnocca Q.Bovey, of

Oincinnati,ia-the county ,of` Hamiltonzand y Y State of Ohio, haveinvented',Qrtainf lmprorvejments'` in Brick-Machines, ofA ng=isa'speciiication ywhich he follow- My improvements are fol-theA cl-assobrick-machines Which-contain a series of molds in the lperiphery, ofacyliny,

The.` irst; ',partof my invention- `consists ing' for'mingfsuch-Jmoldsvin;- a tire-or `bftfnd encir.. clin gfthe body; of; the fwh'eel, whichtire, WhengI ever the molds becometoo-muchworn,by,usen

The" se'cond part `-ofV my invention consists in the provision of driftsor passageswforgthe escape or removal of clay andimiprisonedair from thesides of the .plungers e The third part of my invention consists intheapplication to the sides of the plungers, Within said passages, ofyielding sleeves or scrapers, for detaching and depositing in the saidpassages Whatever clay may be adhering to the sides of the plungers.

The fourth part of my invention consists in the provision of a pressureplate or gage, Whose ofiice is to remove the surplus clay from eachsuccessive mold, and to press the remaining portion compactly into themold, so as to impart a smooth and hard nishto the brick.

Fig. 3 is atransverse section of said machine With its attendant pnlverizer andconveyer. Fig. 4 is a horizontal section at the lineman', with themold-Wheel in relief. Fig. 5 is an enlarged section of a mold-plungerand portion of the xed cam, taken in the plane ot' the mold- Wheelsaxis. Fig. 6 is a section (to the same scale Aas Fig. 5) of thesameparts in a plane of rotation; Fig. 7 is a section taken` at the line YY. Fig. 8 is a perspective view of the fixed cani which actuates theplungers. Fig. 9 is a transverse section of the crushing and pulverizingapparatus. Fig.10 is a horizontal section of said apparatus at the lineZ Z. Fig. 11 shows by side elevation a portion of l the,

My mold-Wheel 'fclose a seri Vs of equidistantradial,apertui the`apertiirlefQB in: @l1 body 4portion' plunger face-plate F is'largerthan th orbedrGnftwplaneet Way of escape for Whatever air or clay mayWork past the face-plate, and which, if notremoved, would penetrate totheinterior of the Wheel and clog the parts.

The chamber H also affords room for the attachment to the portion A of aseries of elastic metallic Scrapers, I, which, embracing theplunger-body, detach therefrom Whatever clay may have adhered thereto,so as to prevent it Working down farther into the Wheel, and, bydiverting it into the chamber H, to enable its ready removal from timeto time. 1n other respects, the above parts, and also the xed cam J,together with the rollers vg', are substantially the same as thecorresponding parts in the brick-machine described in my aforesaidpatent ot' October 20, 1868.

Instead, however, of an additional moldwheel, I impart' the properpressure tothe clay in each mold by means of a plate, K, firmly securedto an adjustable block, L, by bolts M, and the whole secured to theframe by bolts N. The Working-face of the plate K is concavelycylindrical to tit and hug the perphery of the tire C. Strips O,introduced between the block L and the frame, enable, by their removalor insertion, the adjustment of the pressure-plate K toward or from thetire, and thus enable the perfect contact of .partcula-s tra `diesaltedf'iniiily naar yof ',October20, A1,868, h'utQd-ifer's from saidWileel4in?. @para consists gftwocpoptiousm'amly, anji mumportion, A,Who`se rima is'piercedwith` e "B, andl"""` iesof raf these important parts to bemaintained even after they have become reduced by wear.

The pressure-plate K serves to cut o' snperuous clay, and to press theremainderl compactly into the mold with a uniform density and tinish.

In order to thoroughly crush, temper, and eomminute not only the crudeclay but any rocks or other refractory particles it may contain, Iintroduce the clay into a hopper having a pair of cast-iron cylinders,I' P', from which the clay escapes in the form of a sheet, which iscaught and torn topieces by a pair of intermeshing spiked Wheels, Q Q',from which the now thoroughly comminuted clay is conducted by aconveyer, R or R', into the hopper S of the brick-machine, said hopperhaving a series of ribbed wallowers, T T', substantially similar tothose described in my patent aforesaid.

The form of eonveyer shown at R consists of a rotating shaft, V, armedwith spiral blades v, and revolving; axially Within a tube, W, whichextends obliquelyupward from the crushing` and pulverizing apparatus PP' Q. Q to the hopper S. These spiral blades v serve, in conjunctionwith projections w, from the interior of the tube `W, to still furthercomminute the clay in the act of elevating the same to the hopper X is ascraper, and U is an oi-bearer similar to those described in myaforesaid patent.

While describing the preferred forms of my improvements, I reserve theright to vary the same in non-essential particulars. For example, thecrushing and pulverizing apparatus may be placed directly over thehopper S, so as to dispense with a conveyer, or the clay may bedischarged onto a platform and be thence shoveled into the hopper by anattendant.

The tire C may be secured to the body of the mold-wheel by bolts insteadof by keys.

The chambers H may be formed in a moldwheel cast in one instead of twopieces, and such chambers may be used `in a horizontal mold-wheel.

I claim as my inventionl. The provision, in a brick-machine, of theremovable tire C D to the mold-wheel, substantially as and for thepurpose designated.

2. The provision, in a brick-machine, of the chambers H around theplungers, for the objects set forth.

3. The provision, within the chambers H, of the yielding Scrapers I,hugging the plungerbody, for the purpose set forth.

4. The adjustable concave pressure-plate or gage K, in combination Withmold-Wheel A C, block L, bolts M and N, and strips O, as and for thepurpose set forth.

In testimony of which invention I hereunto set my hand.
